Personalised ads are beside the point. The issue is how they are personalised, namely by building a rich profile of user behaviour based on non-consensual tracking.
It isnt even clear that there's a meaningful sense of 'consent' to what modern ad companies (ie., google, facebook, amazon, increasingly microsoft, etc.) do. There is both an individual harm, but a massive collective arm, to the infrastructure of behavioural tracking that has been built by these companies.
This infrastructure should be, largely, illegal. The technology to end any form of privacy is presently deployed only for ads, but should not be deployed anywhere at all.
Your comment is rather light on information that might support your points.
It feels icky, but still I mostly agree. I do think there's a limit as I would consider directly influencing elections (via force or deceit) to be harmful, but I'm largely ok with trying to sway public opinion.

Unfortunately, they were surprisingly effective at the thing I care about which is collecting millions of people's personal information without their knowledge or consent. The fact they turned out to be incompetent does not inspire confidence.
